Preventing Pull-Out from CB-x000 Without Getting a Penile Anchor

I am currently using a CB-6000 and originally chose the KSG-G3, but it seems that no matter which size I select for the KSG, I can still slip out when flaccid. Even worse, it wasn’t very practical long-term as it started causing sores.

I’m really not keen on getting a PA for this. Call me uncommitted, but I truly have no intention of adding any more holes to my body.

Has anyone found or invented a good way to prevent pulling out without needing a PA?

Thanks
